From India, sugar cane was carried through the western regions of Asia into Arabia and later into the countries bordering on the Mediterranean. It was established in Sicily in about A. D. 703 and was carried to Spain in about A. D. 755. As early as A. D. 1,150, Spain had at least 75,000 acres of cane. During this early period sugar cane was grown largely to supply local wants.
